Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2022-27191)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an error in golang.org/x/crypto/ssh before 0.0.0-20220314234659-1baeb1ce4c0b, as used in Go programming language. A remote attacker can crash a server in certain circumstances involving AddHostKey.
2) Resource exhaustion (CVE-ID: CVE-2022-41723)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources in the HPACK decoder. A remote attacker can send a specially crafted HTTP/2 stream to the application, cause resource exhaustion and perform a denial of service (DoS) attack.
3) Resource exhaustion (CVE-ID: CVE-2023-24534)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources when parsing HTTP and MIME headers in net/textproto. A remote attacker can cause an HTTP server to allocate large amounts of memory from a small request and perform a denial of service (DoS) attack.
4) Resource management error (CVE-ID: CVE-2023-24536)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within mime/multipart and net/textproto components when parsing multipart forms. A remote attacker can pass specially crafted request to the application and perform a denial of service (DoS) attack.
5) Infinite loop (CVE-ID: CVE-2023-24537)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop when calling any of the Parse functions on Go source code which contains //line directives with very large line numbers. A remote attacker can consume all available system resources and cause denial of service conditions.
6) Code Injection (CVE-ID: CVE-2023-24538)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to improper input validation in html/template when handling JavaScript templates that contain backticks in code. If a template contains a Go template action within a JavaScript template literal, the contents of the action can be used to terminate the literal, injecting arbitrary JavaScript code into the Go template.
7) Buffer overflow (CVE-ID: CVE-2020-24736)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when executing a crafted SELECT query. A local user can execute a specially crafted query to trigger memory corruption and perform a denial of service (DoS) attack.
8) Input validation error (CVE-ID: CVE-2023-1667)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to multiple errors in kex implementation, related to kex guessing algorithm. A remote attacker can bypass implemented security restrictions.
9) Improper Authentication (CVE-ID: CVE-2023-2283)
The vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to an error within the pki_verify_data_signature() function in pki_crypto.c. The pki_key_check_hash_compatible() function can return SSH_OK value if memory allocation error happens later in the function. The A remote attacker can bypass authentication process and gain unauthorized access to the system.
10) Input validation error (CVE-ID: CVE-2023-24329)
The vulnerability allows a remote attacker to bypass implemented filters.
The vulnerability exists due to insufficient validation of URLs that start with blank characters within urllib.parse component of Python. A remote attacker can pass specially crafted URL to bypass existing filters.
11) Improper Privilege Management (CVE-ID: CVE-2023-26604)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to improper privilege management for some Sudo configurations, e.g., plausible sudoers files in which the "systemctl status" command may be executed. Specifically, systemd does not set LESSSECURE to 1, and thus other programs may be launched from the less program. This presents a substantial security risk when running systemctl from Sudo, because less executes as root when the terminal size is too small to show the complete systemctl output.
12) Input validation error (CVE-ID: CVE-2023-32067)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input when processing DNS responses. A remote attacker can send a specially crafted DNS response to the application and perform a denial of service (DoS) attack.
